Attorney-General (Qld) v Lawrence

The case of Attorney-General (Qld) v Lawrence involved an appeal by the Attorney-General of Queensland against a decision of the primary judge to rescind a continuing detention order imposed on Mark Richard Lawrence under the Dangerous Prisoners (Sexual Offenders) Act 2003. The order had been in place since 2008. The primary judge had ordered Lawrence's release subject to a supervision order, based on expert evidence indicating a decrease in his risk level. The Attorney-General argued that the primary judge should not have rescinded the detention order without evidence that Lawrence was being truthful about the matters upon which the expert evidence was based, and that a supervision order could not adequately protect the community.

The legal issues before the court were whether the principles concerning appellable error in House v The King applied to an appeal against a discretionary decision to release a prisoner on a supervision order, and whether the primary judge properly assessed the adequacy of the evidence and the appropriateness of the supervision order. The court needed to determine whether the primary judge erred in law or made a significant error in assessing the evidence and in determining that a supervision order was sufficient to protect the community.

The court found that the primary judge had erred in law in not assessing whether there was adequate evidence to assume that Lawrence was being truthful about certain matters, and in not considering whether a supervision order could adequately protect the community. The court held that the principles concerning appellable error in House v The King applied, and that the primary judge's decision was open to interference. The appeal was allowed, the orders of the primary judge were set aside, and Lawrence was to continue to be subject to the continuing detention order.
